FAST-ACTING ELECTROMAGNET DRIVE Russian patent published in 2011 - IPC H01H77/06 

FIELD: electricity.

SUBSTANCE: fast-acting electromagnet drive comprises a movable and a fixed contacts, connecting electromagnet, free disengagement electromagnet, disconnecting spring and contact pressing spring. The novelty is the fact that the movable contact is rigidly fixed on the connecting electromagnet anchor and is simultaneously connected by a rigid link to the free disengagement electromagnet anchor, and the contact pressing spring is installed with the possibility of acting at the magnetic conductor of the connecting electromagnet, there is a stop arranged on the free disengagement magnetic conductor, which prevents movement of this magnetic conductor in direction of connected position, and besides, electromagnets are installed on the same axis with the possibility of rotation around this axis.
